6. Maintenance
6.1
UPS Cleaning
Regularly clean the UPS, especially the slits and openings, to ensure that the air freely flows into the
UPS to avoid overheating. If necessary, use an airgun to clean the slits and openings to prevent any
object from blocking or covering these areas.
6.2
UPS Regular Inspection
Regularly check the UPS and inspect:
- whether the UPS, LEDs, and alarm functions are operating normally.
- whether battery voltage is normal. If the battery voltage is too high or too low, find the root cause.
6.3
Battery Replacement
CAUTION
All operations listed in this paragraph must be carried out only by a SKILLED TECHNICIAN.
This definition refers to people who have specific technical qualification and are aware of the methods
of installing, assembling, repairing, and using the equipment safely.
The skilled technician is qualified according to national safety standards to work under dangerous
electrical voltage and uses the personal protective equipment required by national safety standards.
DANGER
A battery can present a risk of electrical shock and high short circuit current.
Before the replacement, it is mandatory the reading of chapter 2 about safety requirements.
Batteries may only be replaced with the same number and type. Batteries must be brand new.
If the battery brand is different from the one originally installed by Legrand, the estimated battery
autonomy indicated on the display of the UPS may not be reliable.
